48460745, Jul 11, 1989

Filed:

Mar 22, 1988

Appl. No.:

7/171906

Inventors:

Bruce E. Block - Caledonia IL

Assignee:

Rockford Automation - Rockford IL

International Classification:

B31B 1300

US Classification:

104166

Abstract:

An improved moving work pallet construction includes a cantilever pallet supported on a single track by a wheel or roller. A drive shaft parallel to the track serves to counterbalance the weight of the pallet and also cooperates with a drive wheel on the pallet construction that is selectively positionable between a rest and a drive position due to coaction with a stop member projecting from the next adjacent pallet or mounted at each work station. In this manner, the cantilevered pallet construction can accumulate on the track as well as stop at a work station where it is possible to lock it into position at the work station.

Abstract:

Adjustable cam actuated switch mechanism of the type in which the switch is operated by a rotating cam means on a timing shaft. The cam means includes a cam plate that is rotatable relative to the timing shaft and the cam plate is adjustably connected to the shaft through a differential gear mechanism including a pair of spur gears of like pitch diameter but having relatively different number of teeth, one of which is drivingly connected to the timing shaft and the other of which is drivingly connected to the cam plate and a pinion gear that meshes with both spur gears and is carried by a housing that encloses the spur gears and which is rotatable relative to the timing shaft to angularly adjust the cam relative to the shaft.
